Wood Pellet Plant

The wood pellet plant is also known as wood pellet line or pellet plant which refers to a set of complete wood pellet mills is used to produce biomass wood pellets on a large scale. Besides the wood pellet making machine, some other auxiliary equipment are also is used in the pelleting process, such as a hammer mill, crusher, hot stove, rotary dryer, cooler, separator, packing machine etc.

Pelletizing Process of the Wood Pellet Plant:

 

Pelletizing Process of Wood Pellet Plant

 

1. Chipping & Crushing:

IIn the wood pellet plant before raw materials are made into biomass pellets, they are first reduced into much smaller, uniformly-sized particles. When the thickness is larger than 10 mm or size is greater than 50*50 mm, a wood chipper is needed to chip these materials into smaller pieces. The hammermill is then used to further crush these small pieces into particles of less than 3 mm in diameter.

Drum Chipper:

The drum chipper is used to cut logs, branches, twigs and planks into perfect high quality chips with even length and uniform chip thickness.

Large Scale Hammer Mill:

The large scale hammer mill is able to produce a wide range of particle sizes. It is easy to use and needs very little maintenance. It is usually used in conjunction with a large scale of wood pellet line.

Small Scale Hammer Mill

The small scale hammer mill is essentially a steel drum containing a vertical or horizontal cross-shaped rotor on which pivoting hammers are mounted. The hammers are free to swing on the ends of the cross.

 



 2. Drying:  

After raw materials are crushed a dryer is needed since most raw wood materials have a moisture content of about 50%. However, the optimal moisture content for pelletiztion is 13%-15%. Therefore a rotary dryer is included in the wood pellet plant to reduce the moisture content. After crushing and drying you can begin making wood pellets.

Rotary Dryer

A rotating drum and strategically positioned flights combine to lift and shower the product evenly through the air stream. A thermostat controller alters the temperature of the air to precisely determine final moisture content and is sensitive to variegate conditions within the product.
 

 

 

 

3. Pelletizing:

 After crushing and drying the raw material properly it is then ready for the pellet mill. The pelletizing machine or press is the key piece of machinery in the wood pellet plant. It should be mentioned that impurities in the raw materials like metal or stone,may damage the die and rollers of  wood pellet making machine.

With a ring shape die and a set of rollers, this wood pellet making machine can not only reduce the wear and tear between die and rollers, but also cuts down on energy consumption.

 

 


4.Cooling:

Usually after pelletizing, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purposes, a cooler must be used to reduce their surface temperature and moisture content.

Cooler

This cooler can cool down all kinds of pellets and can also be matched with secondary volute separator. Discharges pellets automatically via special force  discharge frames.


5. Packing:

Finally is the packing process. In order to protect the wood pellets becoming getting damp and to increase storability, proper packing is necessary. Here we provide you with the best domestic Semi-Auto Packing Machine.

Packing Machine

The automatic bagging machine is composed of an electronic scale, hemming machine and conveyor heat-sealing machine. The scale includes an inlet, filling component and weighing control meter systems.

From raw materials to wood pellets, the main pelleting process including five main procedures, they are chipping and crushing, drying, pelletizing, cooling and packing.
